Four days and counting and the little baby tomato plants start popping out of their seeds and stick up their baby cotyledon" leaves. These will be followed after a while by the true leaves. But it's always great to see the little ones pop out of their seeds and get started.
I've mixed up a gallon of normal strength nutrient but I typically cut it 4:1 with water when I'm first starting. I don't want to hit the little baby tomato plants with too much nutrient strength.
